Monitoring System Of Agricultural Greenhouse Based On Intelligent Internet Of Things Technology

Based on sensor network technology,intelligent Internet of things technology combines many cutting-edge research achievements in the field of network communication and artificial intelligence,greatly improves the operation quality of automatic monitoring system,and has been vigorously promoted in many industries.China is a large agricultural country,but the per capita share of cultivated land is small,coupled with the large climate difference between the north and the south,so improving the utilization rate of limited farmland has always been a research hotspot in the field of agricultural science and technology in China.The extension of agricultural greenhouse has slowed down the tense trend of cultivated land to a certain extent,but at present,it still focuses on the traditional management mode and does not give full play to its due advantages.Problems such as high labor pressure,low production efficiency,untimely temperature and humidity control and large fluctuation of cultivated crop output still restrict the rapid development of agricultural productivity.This project focuses on this problem and proposes to effectively improve the existing greenhouse control system by using advanced intelligent control technology and Internet of things technology.Its main work and achievements include the following points:(1)The demand characteristics of crops for environmental factors were analyzed in detail,and the main objects of environmental monitoring of agricultural greenhouse were determined,namely temperature,humidity,illumination and carbon dioxide concentration.The correlation between the four environmental parameters is studied,the corresponding mathematical model is constructed,and the basic environmental control scheme is designed according to the needs of agricultural production.(2)The intelligent control method is deeply studied.The longicorn whisker bee colony algorithm are proposed to optimize the existing fuzzy neural network PID controller,and applied to the environmental monitoring system of agricultural greenhouse,which significantly improves the control effect.(3)Zig Bee technology is used to build the perception layer platform of greenhouse monitoring system,design the relevant hardware system,complete the selection of various core parts,and design the relevant peripheral circuits to realize the automatic collection and transmission of environmental data in the greenhouse;A simple and efficient remote human-computer interaction interface is designed to realize the monitoring functions of the system.Figure[60] Table[11] Reference[58]...
